In the office.

The computer was humming, and the desktop was messy.

Wang Zhong actively searched for the files, but the actual efficiency was not high.

Mainly because the files were not classified by footprints.

As a type of evidence, footprints were still relatively useful. Imagine a file with a footprint that matched the pattern and wear on the suspect's foot. This could prove that the suspect had been present at the crime scene.

However, using footprints as clues, it was still somewhat insufficient to rely solely on the current files.

Because unlike DNA and fingerprints, footprints did not have a corresponding database.

At this stage, the police database only contained footprints found at the crime scene. They could only be used one file at a time.

Jiang Yuan watched Wang Zhong's actions and couldn't help but speak up, "How about this, can we separate the images of the footprints and take a look? It seemed like it could be done earlier."

"Do you mean only looking at the images of the footprints? Just directly look at the image library?" Wang Zhong didn't quite understand.

Jiang Yuan nodded, "Yes, only the images of the footprints."

"But... can we do without the files?"

"I'll find a footprint that I like first, and then look at the files." Jiang Yuan said.

"Alright." Wang Zhong didn't understand what kind of footprints Jiang Yuan liked, so he found the image library of footprints and flipped through them one by one.

Jiang Yuan stood beside him, looking at the footprints in the images, and information kept flooding his mind.

Height!

Weight!

Age!

Foot shape characteristics!

Gait characteristics!

Wear marks!

Jiang Yuan wanted to find a special footprint.

Using footprints to solve the files was quite difficult, and Jiang Yuan didn't expect to solve one file with just one footprint. That would be unrealistic.

However, Jiang Yuan believed that with such a large image library and so many footprints from crime scenes, he would be able to find one or two strange ones.

"I'll do it myself." Jiang Yuan saw that Wang Zhong didn't have any other actions, so he naturally didn't need him to keep pressing keys there, which would affect his own performance.

Jiang Yuan took over Wang Zhong's position and continued to scan the images slowly.

Wang Zhong was happy with this arrangement.

He just watched Jiang Yuan's actions from the side and thought to himself:

Could it be that he really only has the level of doing homework?

He probably learned it recently, otherwise, he wouldn't have never used it before.

So, his self-taught skills should not be that great.

Wang Zhong was thinking about leaving when suddenly, Jiang Yuan pushed his chair and stood up.

"Take a look at this file." Jiang Yuan gave up his position and gestured for Wang Zhong to take over. He wasn't very familiar with the software here.

Wang Zhong looked at the image of the footprint and his eyes couldn't help but widen in surprise, "Blood footprint?"

Yes, the image in front of him was indeed a pair of blood footprints.

It was well known that it was not easy to create a blood footprint from a minor injury.

We are "pawread.co𝑚", find us on google.

And with serious injuries and a murder case, it would be even more difficult to solve the files.

Even if it was easy to solve the files back then, it would probably be difficult now.

Wang Zhong sat back in his position, opened the files, read a few lines, and quickly handed it back to Jiang Yuan.

Yan Ge, who was also in the office, heard about the blood footprints and walked over to take a look.

Jiang Yuan didn't hesitate to sit down and started reading the files.

The files were not complicated. It was about a man named Yang from Shanghe Village in the suburbs. He was found dead in his home, and the murder weapon was his own sickle. There were bloodstains on the sickle, but no fingerprints.

In addition, usable fingerprints and DNA were not collected at the scene, but there were a large number of footprints.

In the early stages of the investigation, it was suspected to be a dispute among villagers, so everyone in the village was questioned and their statements were recorded. Footprints from the entire village were also collected and compared, but nothing was found.

Later, the investigation shifted to a burglary, speculating that the thief was discovered and in a panic, escalated to murder and fled.

The responsible detective then thoroughly investigated all the nearby thieves and focused on those who were active in the early stages but disappeared later, but the files remained unsolved.

Jiang Yuan read through all the blood footprints and then opened the analysis of the footprints.

As expected, the analysis of the footprints was over a hundred words long, clearly done by experts.

"Chen Wenming, the forensic expert at Qinghe City Bureau, is quite famous for his work on footprints. He was the one who analyzed these footprints." Jiang Yuan had a clear memory of the files he had handled in the past ten years, and the footprints were all ones he had dealt with.

Jiang Yuan made a sound of agreement and first scanned the conclusions:

Height: 178-185 cm.

Age: Between 18-23 years old.

Consistent footfall direction; the shape of the pressure marks on the sole and heel were basically the same.

There was no judgment on weight, but the judgment on age was quite long: among the footprints, the stride was large, the steps were agile and powerful, the step angle was small, the step width was narrow... the pressure marks were heavily concentrated on the inner side of the forefoot, and the pressure marks were towards the front... estimated age range was between 18 and 23 years old.

The height was determined by the length from the front edge of the toe mark to the back edge of the heel mark, in other words, it was determined by the length of the foot.

This contradicted Jiang Yuan's judgment on the footprints.

However, it was appropriate to have contradictions. If it completely matched, then Jiang Yuan's judgment would not be helpful for the files."Find out who the officer in charge is, I'll give him a call for some information." Jiang Yuan expressed himself humbly.

This time, Wang Zhong saw through Jiang Yuan's "humility" right away. As he found the phone number, he carefully reminded, "It's Captain Wu Junhao from the first squad. Captain Wu has quite a temper, so don't be too blunt."

"Alright." Jiang Yuan had a deep impression of the burly Captain Wu Junhao.

Once the call was connected, Wu Junhao's loud voice came through the receiver, "Forensic Jiang, do you have another good case for me?"

Jiang Yuan frowned at the screen, simply switched to speakerphone, and said, "Captain Wu, I've come across a case file that you handled before, and I'd like to discuss it with you."

"Oh, you mean... Follow that bastard, go around from the front!" Wu Junhao roared, then changed his tone and laughed, "I'm in the middle of an arrest, go ahead."

Jiang Yuan said, "Do you remember the murder case of Yang Qian from Shanghe Village?"

Wu Junhao was clearly taken aback, "Why are you suddenly bringing up this case? What did you find?"

"I've examined the footprints in the case file, and I believe the killer's height should be quite unique. My judgment is that the killer is likely to be 193 centimeters tall. A very conspicuous height." This was why Jiang Yuan chose this case.

The average height of people in Shannan Province is not low, and men of 180 centimeters can be seen everywhere on the street. However, no matter what, 193 centimeters is a standout height, which can greatly narrow down the range of suspects.

On the phone, the sound of panting and running suddenly stopped.

Wu Junhao asked, "193 centimeters is quite tall. Chen Wenming estimated it to be 180, possibly up to 185. How confident are you..."

Jiang Yuan said, "The length and width of sports shoes are slightly larger than leather shoes, of course, this is a non-essential difference..."

"But starting from this point, I believe the sports shoes the killer wore that day were a bit small..."

"Also, the size of the killer's own feet may be smaller than the normal proportion..."

Jiang Yuan paused here, and directly asked, "When you were handling this case, were there any suspects of the height 193 centimeters?"

Wu Junhao seemed to have fallen into recollection.

After a long while.

Accompanied by the noise on the phone, Wu Junhao said, "I need to go back and check my notes."

Jiang Yuan reminded him, "If it's 193 centimeters, you should have an impression when you see it."

"Right, I'll check my notebook first." When faced with a specific case, Wu Junhao suddenly became serious.

Jiang Yuan had no choice but to agree. Then, he thought of those in movies and TV shows who always get killed just in time when they go to get important evidence... He quickly warned, "Be careful."

"Alright." Wu Junhao responded loudly, then took his phone away and shouted, "Catch that little bastard for me, no dinner if you can't catch him!"

"This kid runs faster than a rabbit."

"Then you guys act like dogs and corner him for me!"
